WebJun 4, 2024 · For growth of a plant to actually occur, the photo-assimilates synthesized in leaves must be exported to growing sink tissues. Up to 80% of fixed carbon is exported via phloem translocation in the day and night periods ( Grange, 1985; Geiger and Servaites, 1994; Lemoine et al., 2013 ). WebJun 19, 2024 · Clopyralid and aminopyralid absorption and translocation were quantified in nonvernalized and vernalized plants following application of 14C-labeled herbicides 2, 4, 8, 24, and 72 h after treatment. ... The changes in source–sink competition contribute to higher levels of photoassimilate translocation to the roots in the fall (Tworkoski 1992).
